2 Claims.

This invention relates to slide cartridges for pencils or othersupports, and has for an object to provide an improved constructionwherein a flexible rubber eraser, lip stick, or other article 5 may becarried by the end of a pencil or similar shaped support and beprotected both when in use and when not in use.

Another object is to provide a pencil or other cylindrical support withan extension at one end formed of flexible rubber, lip stick, or othersubstance, together with means for holding the eraser or other articlein place and a tubular protecting member telescopically fitting over thepencil, support and rubber eraser.

A further object of the invention is to provide for pencils and thelike, an elongated elastic rubber eraser at one end, with a protectingsleeve open at both ends telescopically mounted in position so that fromtime to time it may be telescoped over the pencil and thereby exposemore and more of the free end of the eraser.

In the accompanying drawing-- Figure 1 is a side view of an embodimentof the invention shown applied to a pencil;

Fig. 2 is an enlarged view partly broken away for showing certain detailstructure not illustrated in Fig. 1.

As shown in the accompanying drawing, the invention has been applied toa pencil either 3 round or hexagonal. However, it will be understoodthat the invention could be applied to cylindrical objects not formed aspencils.

In the drawing, l indicates a hexagonal pencil which is provided with ametallic holder 2 having portions crimped or pressed inwardly to thepencil body and certain parts 3 pushed appreciably into the wood of thepencil l for firmly holding or looking the holder 2 in place. The holderprojects past the pencil body I and forms a tubular socket for thearticle 4. The article 4 is shown as a round flexible rubber eraser, buta lip stick or other article could be substituted without departing fromthe spirit of the invention. Normally the cap 6 is arranged in positionas 4 shown in the drawing to protect the upper or free end of theeraser, but thiscap is removed when the eraser is to be used. The sameis true if a lip stick is substituted for the eraser. It will thereforebe understood that where the expression eraser. or fiexible rubbereraser is used, the term includes a lip stick or other desirable articlewhich may be substituted for the eraser. A cover or sleeve 1telescopically fits over the eraser 4, holder 2, and part of the pencilbody I.

5 Normally the parts are arranged as shown in the drawing when the partsare new.

The knurled portion 9 on sleeve 1 acts as a desired finger hold and alsowith beads l and I I to sufficiently stiffen or reinforce the slide. Thebead l0 also acts as abutment or stop for the cap 6 which cap is alsoprovided with a reinforcing bead 12. The sleeve! is formed with one ormore pressed-out burrs or portions It at the top so as to frictionallyhold the cap 6 in' place. At the bottom one or more burrs M are pressedout which frictionally engage sleeve I for preventing any accidentalmovement thereof. The burrs l4 are pressed from the holder 2 while spursl3 are pressed from sleeve 1. As the eraser is used in this form of theinvention the sleeve 1 may be moved downwardly from time to time untilthe shoulder l5 strikes the upper end of holder 2. If it is desired touse as much as possible of the eraser, sleeve 1 iscompletely removedfrom the pencil, preferably by a pull in a direction away from thepoint. It will be understood that the holder 2, sleeve 1 and cap 6 maybe made from metal, rubber, Bakelite, wood, Celluloid, or othermaterial.

While a certain form of holder 2 has been shown, it will be understoodthat other forms may be used without departing from the invention, theessential feature being to secure an eraser to the body I whilepermitting the sleeve '1 to readily telescope thereover. The sleeve 1 isheld in place as is also the cap 6.

I claim: I l. A slide cartridge for pencils comprising metal holdersecured to the pencil for holding an article at one end of said pencil,said holder being formed with pressed-in parts extending into saidarticle for holding the article against removal pressed-in partsextending into said pencil for securing the holder to the pencil andpressedout spurs at one end, and a tubular cover telescopicallyfittingover said article and frictionally engaging said spurs, saidholder and part of said pencil, said cover being adapted to be slidlongitudinally over more and more of said pencil as more and more ofsaid article at its free end is worn away, said spurs acting to preventaccidental movement of the cover in respect tothe holder.

2. In an eraser mounting, a tubular metal holder formed with meansadapted to interlock with one end of an eraser, said holder having anoutwardly extending spur and a cover slidingly mounted over said eraserand said holder positioned to frictionally engage said spur whereby thecover may be held in different adjusted positions, said cover at itsouter end being constricted to fit said eraser for preventing unduebending thereof, said constricted portion having an outwardly extendingcap-receiving spur.
